◆Container queries can now be specified by name only.
Chrome 148 introduced 'name-only container queries,' which allow you to specify a CSS query container using only the 'container-name.'
Previously, when using '@container,' it was necessary to specify the 'container-type' in addition to the container name. Starting with Chrome 148, you can now execute container queries using only the container name, without having to set the container type.
By allowing container queries to be specified using only the container name, it has become easier to specify styles that are context-aware for components.
◆Delayed loading of video and audio is now possible.
Chrome 148 added a 'loading' attribute to the video and audio elements. By specifying 'loading='lazy'', you can delay the loading of videos and audio until the element is close to the viewport.
This feature is similar to the lazy loading already used in img and iframe elements, and is said to help improve page loading performance and reduce data usage.
◆ Browser-based AI can now be used from websites.
Chrome 148 introduced the 'Prompt API,' which allows web developers to directly access on-device AI models embedded in the browser. Chrome uses '
Chrome 148 supports text, image, and audio input. The generated text adheres to predefined regular expressions and JSON schema formats.
The Prompt API enables features such as image caption generation, image search, audio transcription, sound event classification, text generation based on instructions, and information extraction from multimodal materials. A demo site is also available, allowing you to try out text-based responses.
By typing 'chrome://on-device-internals' into the Chrome URL bar and clicking the 'Model Status' tab, you can check the model's name, version, location, size, and other information.
◆Web Serial API is now available in Chrome for Android.
Chrome for Android now supports the ' Web Serial API ,' an API for connecting to serial ports on PCs and other devices, as well as USB and Bluetooth devices that function as serial ports.
